Hi friend,<\/p>\n

I am\u00a0writing\u00a0this article after very long duration. Have lots of tips to share from my toolbox, so here few about the dynamic creation of URL in ASP.NET:<\/p>\n

lets say, you have to register the javascript file from code behind, then you may need a full path for that js file in format “http:\/\/yourdomain\/jsfolder\/jsfilename”<\/p>\n

one way to achieve this is like :<\/p>\n

\n"http:\/\/" Request.ServerVariables["HTTP_HOST"] + "\/jsfolder\/jsfilename.js";\n<\/pre>\n
In above snap you can see that HTTP_HOST is used. This server variable returns the address of your domain. Still, above code is not 100% functional.protocol may be http <\/strong>or https<\/strong>.<\/p>\n
<\/p>\n
To get the exact protocol, we need to check that connection is secured or not.
\nbelow is small utility to find that connection is secured or not:<\/p>\n
\n        \/\/\/ <summary>\n        \/\/\/ Gets if the url is secure or not\n        \/\/\/ <\/summary>\n        private bool isSecureURL\n        {\n            get\n            {\n                \/\/ Check the request\n                if (HttpContext.Current.Request.IsSecureConnection ||\n                    (HttpContext.Current.Request.\n                     ServerVariables["HTTPS"] != null &&\n                    HttpContext.Current.Request.\n                    ServerVariables["HTTPS"].ToLower() == "on"))\n                    return true;\n                if ((!string.IsNullOrEmpty(HttpContext.Current.Request.\n                    ServerVariables["HTTP_HOST"].ToString())) &&\n                    (HttpContext.Current.Request.\n                      ServerVariables["HTTP_HOST"].ToString().\n                      EndsWith("443")))\n                    return true;\n                \/\/ url is not secure:\n                return false;\n            }\n        }\n<\/pre>\n
In code check whether above property returns true or false. if its true then use https <\/strong>or use http <\/strong>protocol.<\/p>\n
In my application, the above code behaves unexpectedly.
\nin case of http protocol, every thing is fine; but in case of https protocol, the base path of website repeats like below line.<\/p>\n
https:\/\/yourdomainhttps:\/\/yourdomain\/jsfolder\/jsfilename<\/strong><\/p>\n
<\/strong>
\nSo, the another and simplest approach i have used and which is working great is the ResolveUrl <\/strong>method of the page.
\nso the above code snap can easily written like :
\nPage.ResolveUrl(“~\/jsfolderName\/jsfileName.ja”);<\/strong>
\nThe advantage of above approach is that no need to find the host name or protocol, every thing is taken care.
\nWhile reading, i found one good article on using this approach and its advantage at this site<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
